Interest in calcium has continued since the 1980s when its role in promoting bone growth and retention was established in clinical trials of children and postmenopausal women. The human nutrition functions now attributed to calcium have expanded beyond bone health to include other conditions such as body weight maintenance. While most efforts have been focused on the findings that dietary intakes are low, there are emerging data on safety concerns of excess amounts. This Special Issue on calcium nutrition, spanning the lifecycle from critically ill neonates through to older adults, has been written by some of the leading researchers in this field.

This special issue of Nutrients records seven of the presentations made to the very successful meeting titled “Osteoporosis Prevention: A Workshop on Calcium, Vitamin D and other Nutritional Aspects” held in Adelaide, Australia on 5 and 6 March 2010 [1-7]. Seventy six delegates attended from across Australia and New Zealand to review the current evidence that dietary calcium intake, vitamin D status, other nutrients and exercise play a significant role in bone mineral homeostasis and act to prevent the development of osteoporosis. The Workshop promoted the concept that osteoporosis is a predictable and preventable disease and that significant benefit would be achieved to reduce the incidence of osteoporosis and the risk of fractures from nutrition and life style activities. Such an achievement will not only save considerable pain, suffering and morbidity but will also have a major financial benefit for the healthcare system for which the cost of treatment for osteoporotic fractures already amounts to billions of dollars.

It has been suggested that the dietary intake of antioxidant supplements could be a useful strategy to reduce the incidence of diseases associated with oxidative stress. The aim of present work is to study the possibility to obtain compounds with antioxidant activity from wine wastes using water as solvent. Results have shown that it is possible to obtain flavan-3-ol compounds from wine wastes both from V. vinifera (cv. Cabernet Sauvignon and Merlot) and V. labrusca (cv. Bordo and Isabella) species. The main phenolic compounds found in the extracts were catechin and epicatechin, followed by procyanidin B3, procyanidin B1, procyanidin B2, gallic acid, epigallocatechin, and procyanidin B4. All flavan-3-ol extracts showed significant in vitro and in vivo activities. It was found that the extracts were able to prevent lipid and protein oxidative damage in the cerebral cortex, cerebellum and hippocampus tissues of rats. Although further studies are necessary, these flavan-3-ol extracts show potential to be used to reduce the incidence of degenerative diseases associated with oxidative stress.

There have been many publications in recent years reporting on the quantity of physical activity among college students using indirect indicators such as steps walked per day or time spent on physical activities. The purpose of this study was to describe the trends of physical fitness related to BMI and body fat among university students between 1996 and 2008. The results showed a significant decline in the average fitness levels measured as an estimation of VO2max for male and female students (p < 0.001 for both sexes). The linear trend for BMI by years was not significant for both sexes (p for males = 0.772, p for females = 0.253). On average, in the last 13 years, % body fat was increasing 0.513%/year for males and 0.654%/year for females. There is a significant indirect correlation between the student’s VO2max levels and % body fat, r = −0.489; p < 0.001 for males; and r = −0.416, p < 0.001 for females. Approximately 23.9% of the variance in the VO2max levels in males and 17.3% in females can be explained by the variance in % body fat. The results support recent findings that physical fitness among college students is declining and body fatness is increasing.
